Bottom Roller Replacement
These instructions are only for replacing the rollers that are supported by the bottom brackets. This roller can be found just a few inches off the ground when the door is closed. For additional roller replacement instructions, visit our Top Roller Replacement or our Middle Roller and Hinge Replacement tutorials.
Replacing the bottom roller on a garage door can be extremely dangerous for do-it-yourselfers when done incorrectly. When you install a new roller, do not loosen the bolts that secure the bottom fixture to the garage door. Additionally, do not remove the cable from the bottom fixture. Failure to adhere to these warnings may cause the door to cock, jamb, or fall, resulting in property damage and/or personal injury or death.
We have also made a video to help you replace your garage door rollers in order to provide you a more audio-visual option while preparing to do your repair. Caution: The video was NOT designed to REPLACE the instructions below. The video is designed to INFORM the instructions. Protect yourself from serious injury and your property from further damage by reading all of the instructions below in addition to watching the video.
